1 Automation Task

1.1 Overview

Introduction

In order to diagnose communication connections which are configured for data exchange via an Industrial Ethernet communication module (CP) of S7-300, the NCM S7 diagnostic is normally used. The NCM S7 diagnostic tool is integrated in STEP 7 and provides a clear overview of the status of the configured communication connections. The disadvantage here is that the status information of the NCM S7 diagnostic cannot be visualized on an operator panel or a control system.

In this application example we show you how the status of the communication connections in the user program of the CPU can be determined and visualized on an operator panel with little configuration and programming workload.

Overview of the automation task

The figure below provides an overview of the automation task.

Setup

The S7-300 stations A and B are connected at the Industrial Ethernet network via communication processors (CP343-1). The data exchange between the S7-300 stations A and B occurs via several, different communication connections with standard functions.

The function blocks FB170 “SR_DIAG” and FB171 “S7_DIAG” supplied with this application are implemented in the user program of S7-300 station A. These compact function blocks determine the status information of the communication connections, which have been configured on S7-300 station A for the Industrial Ethernet CP343-1.

Table 2-1 gives an overview of the communication connections and standard functions configured and programmed on S7-300 station A for the data exchange via CP343-1.

Determining the maximum number of configurable SEND/RECEIVE connections

The maximum number of configurable SEND/RECEIVE connections is determined automatically. When calling the FC10 “AG_CNTRL” with the input parameter CMD=1 the value of the output parameter STATUS is evaluated.

If the value of the output parameter STATUS provides the value 8186H, then the maximum number of configurable SEND/RECEIVE connections is determined via the connection number specified at the input parameter ID and stored in the instance data block DB170 (see Table 3-6).

3.1.3 HMI interface

The data required for the visualization is stored in the instance data block DB170 in the following tags (see Table 3-6). These tags are integrated into WinCC flexible and form the HMI interface. This enables displaying the data stored in the tags at the HMI Multi Panel or the tags can be set by the HMI Panel.

3.1.4 Functions

The tags of the instance data block DB170 listed in Table 3-12 are implemented in the details view of the SEND/RECEIVE connection diagnostic and can therefore be controlled via the HMI Multi Panel to realize different functions.

If the tags are controlled to value “true” a job for resetting, stopping or starting a certain, selected SEND/RECEIVE connection is initiated.

Table 3-12

Tag Data type Function

HMI_CONN_STOP Bool 0: no function 1: STOP (stop the connection)

HMI_CONN_START Bool 0 = no function 1 = START (start the connection)

HMI_CONN_RESET Bool 0 = no function 1 = RESET (reset the connection)

Reset the connection (RESET)

If the HMI_CONN_RESET tag of the type BOOL has the value “true”, then the FC10 “AG_CNTRL” is called with input parameter CMD=2. This resets the connection specified at the input parameter ID via the connection number.

If the job was completed successfully or with error, then the HMI_CONN_RESET tag is reset to value “false”.

If the job was completed with error, than there is an additional error evaluation (see chapter 3.1.5 “Error evaluation”).

Stop the connection (STOP)

If the HMI_CONN_STOP tag of the type BOOL has the value “true”, then the FC10 “AG_CNTRL” is called with input parameter CMD=6. This stops the connection specified at the input parameter ID via the connection number.

If the job was completed successfully or with error, then the HMI_CONN_STOP tag is reset to value “false”.


Start the connection (START)

If the HMI_CONN_START tag of the type BOOL has the value “true”, then the FC10 “AG_CNTRL” is called with input parameter CMD=7. This starts the connection specified at the input parameter ID via the connection number and which was previously stopped with CMD=6.

If the job was completed successfully or with error, then the HMI_CONN_START tag is reset to value “false”.

Value range of the maximum number of S7 connections

In FB171 “S7_DIAG” it is checked whether the maximum number of diagnosable S7 connections is in the valid value range 1 to 64 (dec). The maximum number of S7 connections is stored in the instance data block of FB171 in the Max_connection tag of data type integer.

If the maximum number of S7 connections lies outside the valid value range, then the MAX_connection tag is set to value 64(dec). The maximum number of diagnosable S7 connections is therefore limited to 64(dec).

Determining the connection status for the display in WinCC flexible

For each connection number in the value range from 1 to 64 the function FC62 “C_CNTRL” is called and the job result of the output parameters C_STATUS and C_CONN is evaluated.

The job result of the output parameter C_STATUS and C_CON, which contains information on the connection status, is evaluated and structured filed in the instance data block DB170 (see 3.2.3 “HMI interface”).
